hi peeps new to the site, bought my car the other day. its an xr3i efi converted to turbo with a full fiesta turbo engine and ofac loom. running a T3.

basically its running really rough at idle and not pulling properly. also intermittantly when cruising at motorway speeds and floor it the car shakes and goes nowhere.

put a snap on scanner on it and had two fault codes. 47 - map sensor or cicuit fault and 59 - co potentiometer out of limits

does this mean it deffo needs a map sensor and potentiometer?

cheers chris
